“Call Me Maybe” the pop song of the summer has all the classic components of a hit pop song. It says the refrain over and over. It seems to have appeal to all age groups, to the point where general Colin Powell was seen singing it on CBS this morning. Tweeting by Justin Bieber didn’t hurt. Carly Rae Jepsen does have the sound and style of Taylor Swift in this song. Will she be a one hit wonder? Hard to say, but she’s on the cover of Billboard magazine this week and she has made a lot of the world happy.
